'arrogate' originates from Latin, specifically the word 'arrogare', where 'ad-' meant 'to' and 'rogare' meant 'to ask/request'.

'arrogate' changed from the Latin verb 'arrogare' (past participle 'arrogatus') and was borrowed into English in the late 16th century (via scholarly/late Latin usage), eventually becoming the modern English 'arrogate'.

Initially, it meant 'to ask for or claim (by asking)', but over time it evolved into its current sense of 'to claim or appropriate (something) without right'.
